Improvement in purifying paraffins



U NITED STATES P TEW FRANCIS X. BYERLEY, OF CLEVELAND, OH IO.

IMPROVEMENT IN PURIFVING PARAFFINE.

To all evhom it may concern:

Be it known that I, FRANCIS X. BYERLEY, of Cleveland, county of Ouyahogaand State of Ohio, have invented an Improved Process for ObtainingParaffine fax from Parat'tine Oil, and for ltefining the same, of whichthe following is a specification:

Take the paraffinized oil which has been chilled in the usual1na-nner-if it is in a solid mass it should be broken up into fragmentsby any suitable meansand place it in an open vessel with a perforatedfalse bottom. This false bottom should be covered with canvas or othersuitable straining medium, and closely fitted to the sides of the vesselat a short distance from the main bottom. Should it be desired topreserve the temperature of the chilled mass during the process, thisvessel should be surrounded by a larger one and the space between themfilled with a cooling-mixture. The vessel containing the chilled mass ofparaffinized oil is connected below the false bottom with a pump orother contrivance for drawing oifthe oil as it drains away from themass. After the chilled oil has been placed in the vessel aforesaid thepump is set in motion and the oil is thus carried off, leaving theparaffine wax in its crude state above the false bottom.

To refine this wax, naphtha, gasoline, or any other solvent ofparafiine, or the oil, is sprinkled over it. The pump being keptconstantly in motion, the solvent and the parts dissolved are thuscarried off, the action of the pump accelerating the filtration. Thesprinkling and pumping is continued until the par affine has beenrefined to the desired point.

Should the object be to refine crude paraffine obtained in any othermanner, the paraffine should first be ground in the usual Way, and thenplaced in the vessel with the false bottom and treated as abovedescribed.

This process may be applied to all analogous substancessuch as lard,stearine, Ste-with like results, and is a very quick and efiicientprocess.

I claim- I The improved process of obtaining or separating paraffine waxfrom the oil by the action of a pump, connected with the receiver inwhich the paraffine is placed, at a point below the perforated falsebottom, substantially as herein described.

F. X. BYERLEY.
